WILSONIA ROTUNDIFOLIA. 2, sp. 
Foliis ovato-rotundatis pilosiusculis, ramis calycibusque sub- 
cylindraceis dense hirsutis, floribus axillaribus terminalibusque 
solitariis. 
Has. Australia, Swan River Settlement. Mr. J. Drummond. 
I am doubtful whether to refer this little plant to Mr. Brown’s 
genus Wilsonia or to Cressa. It has not the deeply cleft calyx 
of the latter, nor indeed the urceolate calyx, nor distichous 
leaves of the former. The true Wilsonia humilis of Mr. 
Brown is figured in our Icones Plantarum at vol. 3. tab. 265. 
The habit indeed of both these plants is extremely similar to 
that of Frankenia. In our plant the cells of the ovary are 
generally 2-seeded; but the seeds are abortive.
